@l0cation_unknown: The route of this Derbyshire cave system begins with a vertical shaft entrance and continues through a low crawl. One of its best known features is the 'Pearly Gates', where two stalactitic calcite pillars stand so closely together that cavers must squeeze sideways between them. I measured the narrowest point to be around 7 inches and the largest being no more than a couple inches wider. Beyond this constriction, the cave descends into a high rift and eventually reaches blocked passages and boulder chokes. #urbexuk #caving #cavinguk #peakdistrict #peakdistrictcaves
